The AirTAC GC300C15AC2W AirTAC F.R.L. Combination, PT1/2 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300C15AC2W is an AirTAC GC-series three-unit F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate down to 5 um, a standard regulator holds downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) adjustment range, and a lubricator meters oil mist into the air line for downstream pneumatic components. This configuration is built around a 1/2 in PT port, carries an automatic drain on the filter bowl so collected condensate is expelled without manual attention, and is fitted with an external round gauge reading in psi; the embedded square gauge is the standard option and MPa/psi/bar scales are available. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT as order options) and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-C1 filter, GR300-C1 regulator and GL300-C1 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

On a stamping or assembly cell with air-operated clamps and a small pneumatic press, this unit cleans the shop air to 5 um, holds the clamp pressure set on the psi gauge, and feeds oil mist to keep cylinder seals working.
On a carton packaging line where diverters, pushers and lift-gates run on air cylinders all shift, an automatic drain keeps condensate out of the valves during continuous running while the regulator pins a stable working pressure.
At a machine shop drop feeding impact wrenches, grinders and air drills, this three-unit set filters cutting-air moisture to 5 um, regulates line pressure for tool life, and lubricates the tools through the mist lubricator.
Start with the port and size step: this unit is the 300 size with a 1/2 in PT port, one step up from 1/4 in and below the 400/600 sizes - match the size to the air consumption of the machines on the line rather than to the pipe thread alone, and note that larger sizes carry more flow. The 5 um filter grade (code W) is the finer of the two published grades, the 40 um grade being standard, so choose 5 um where downstream valves and cylinders need cleaner air. The automatic drain (code A) suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives. The round psi gauge is fitted here; square embedded gauges and MPa/bar scales are options. PT is the standard thread, with G (BSPP) and NPT as orderable options, and a mounting bracket is included.
Because AirTAC publishes flow as curves and not as a single rated number, we do not quote a flow figure here. Send us your application's air demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC300 series as curves rather than a single rated figure, so we do not quote a flow number here. Tell us your application's air demand and working pressure and we will confirm the flow from the datasheet on request before you order.
The W in the code sets the filter element to the finer 5 um grade instead of the standard 40 um, and the A sets an automatic drain that expels collected condensate from the filter bowl without manual attention. Manual and differential-pressure drains are the other published drain options for this family.
